    Summary form only given. A series of findings and hypotheses derived from six years of model-based experimental research in team decision making and coordination are reported. The main hypothesis is that team coordination strategies evolve from explicit coordination under low workload conditions to implicit coordination as workload increases. Explicit coordination involves the transfer of informat... View full abstract»
